Patented June 24, 1930 Fries JENS P. NIELSEN AND JOSEPH R. HIGHER, OF CHICAGO, ILLINOIS, SAID HIGHER ASSIGNOR TO SAID NIELSEN END CLOSING AND PROTECTING MEANS FOR FABRIC ROLLS Application filed December 22, 1927. Serial No. 241,742.

The invention relates to a device for closing and protecting the ends of rolled material such as roofing paper and the like. Such a device commonly consists of a pair of end plates for the roll and a tie rod extending through the bore of the roll and connecting the end plates together. Our invention re lates more particularly to a novel construction of the tie rod for anchoring the ends thereof to the end plates.

The object of our invention is to provide an improved connection between the tie rod and the end plates, which renders the device.

economical in the use of materials, capable of being maiuifactured at a low cost, adapted to be quick. y and easily applied to a roll, and rugged and effective in use.

In carrying out our invention, we form the connection between the tie rod and either end plate by squeezing or compressing a small pieceof metal onto the end of the tie rod after passing through the end plate, so as to provide a head thereon incapable of passing through the end plate. By this construction it is possible not only to use a tie rod in the form of a wire of small diameter, but it is also possible to use end plates of relatively thin gage sheet metal. This is advantageous because it reduces the cost of the material, and also reduces the weight of the device, rendering it possible to increase substantially the number of devices contained in a shipment of a given weight. In prior constructions it has been found necessary to employ rods of substantial thickness owing to the methods employed in fastening the rods to the end plates.

In the accompanying drawing, we have illustrated our invention as applied to a tar paper roll in the bore of which is contained a number of packages as is usual in the art, which packages are held in position by means of a tie rod connecting the end plates and placed under tension.

Figure l of the drawing is a longitudinal sectional View showing such a roll with the end closing and protecting device applied thereto.

Fig. 2 is a fragmentary elevation section illustrating on a larger scale the construction employed.

' Fig. 31s a transverse sectional. view showing the metallic part after it has been squeezed onto the rod, being taken in the plane of line 83 of Fig. 2.

Fig. 4. is a similar View before the squeezing operation.

p In Fig. l, the tar paper or other fabric roll 1 has the usual central bore 2 within which are located a plurality of packages 3 containing the usual material such as cement, nails, etc, for use in the application of the rolled material. I

The end closing and protecting device comprises a pair of inwardly dished end plates 4:, centrally apertured at 5 and connected by means of a tie rod 6 having the opposite ends passing through said apertures 5. On each end of the rod 6 is clamped a metallic block constituting a head 7. The heads 7 at opposite ends of the rod operate to hold the plates firmly against the ends of the roll, the rod being under tension. y

In practice the end closing and protecting device is usually supplied to the manufac-- turers of the tar-paper roll with the end plates detached. That is to say, the end plates 4 are assembled in quantities, in nested relation, the tie rods 6 being detached from the end plates. As herein shown, one end of the tie rod as thus supplied has a head 7 rigidly secured thereto, and in the assembling of the two end plates and rod in a roll, the rod is first passed through one end plate shown at the left in Fig. 2, and then through the other end plate at the opposite end of the roll, whereupon a head 7 is clamped on the projecting end of the rod so as to engage with the end plate. In this operation, the rod is placed under tension while the apertured block is squeezed or compressed into engagement with the rod, both the block and the rod being distorted so as to effect the desired 'interengagement. To facilitate the distortion of the block, it is preferably made relatively soft or malleable, and moreover is notched at opposite sides as at 8 to weaken the same. The rod likewise is relatively soft, so that in the distortion of the block the rod becomes flattened slightly as shown in Fig.

3. Obviously the rod may be supplied in any length desired, it being only necessary to cut oif the unused portion after the final 5 head has been clamped in position.

The means employed for clamping the heads 7 on the rod may be of any suitable character forming no part of the present invention, and therefore not herein illustrated 10 and described. here the device is shipped to the manufacturer of the rolls for application thereto, the latter will be supplied with a suitable tool.

While We have herein shown the tie rod at both ends of the roll provided with heads 7, it will be understood that the invention is not limited to this construction, it being obvious that one end of the rod may be anchored to the corresponding end plate in any 0 preferred way, according to the desires of the manufacturer. In other words, our invention has especial reference to the final operation in applying the device to a roll, namely, the clamping of the head 7 on one end of the rod after it has been passed through the roll and both of the end plates.

e claim as our invention:

1. An end closing and protecting device for a fabric roll comprising a pair of end plates adapted to engage opposite ends of the roll, and a tie rod having one end anchored to one of the end plates and its other end passing through the other end plate and pro jecting a short distance therefrom, said projecting portion of the tie rod having a metallic block secured thereon in position to hold the rod under tension, said block and rod being compressed transversely so as to effect their interengagement with the block engag ing the last mentioned end plate.

2. An end closing and protecting device for fabric rolls comprising a pair of end plates adapted to engage opposite ends of the roll, and a tie rod having one end anchored 5 to one of the end plates and its other end passing through the other end plate and projecting a short distance therefrom, said projecting portion of the tie rod having a metallic block secured thereon in position to hold the rod under tension, said block being apertured to receive the rod and notched to Weaken the same whereby the block may be compressed into clamping engagement with the rod.

In testimony whereof we have hereunto aflixed our signatures.
